I uninstalled and reinstalled and Firefox for windows 7 does not open. There is no error message - it just does not, even in safe mode. What should I do?

My computer is set to the automatic update in Windows 7 Home Premium and Microsoft Office Professional Plus 2010. I am also running Norton 360. There was a major update for the office on 10-12-14, which seems to be at the start of my problems. This month, whenever my updates caused a restart, Mozilla has failed to open. I uninstalled and reinstalled several times, and it lasted only a day or two before it crashes again. This last time it is still not open. All instructions to solve problems appear to be based on the idea that the program is open and just questions. I can't even open it in Mode without failure.

I tried to reinstall, and it says it will launch automatically when the installation is complete, but it does not work. As Norton scan every download before it works, I am not sure if this is the problem since I never get the window that indicates the setup step by step for Firefox.

What should I do?


Some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files, and then reinstall Firefox. A clean reinstall is not the same as a regular resettlement performed using built-in installer. Please follow these steps:

Note: You can print these steps or consult them in another browser.

  1. Download the latest version of Firefox from mozilla.org office (or choose the download for your operating system and language on this page) and save the file to install it on your computer.
  2. Once the download is complete, close all Firefox Windows (or open the Firefox menu

    Click the close button


  3. Remove the Firefox installation folder, which is located in one of these locations, by default:
    • Windows:

      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x 86) \Mozilla Firefox
  4. Now, go ahead and reinstall Firefox:
    1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
    2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

More information on the resettlement of Firefox can be found here.

WARNING: Do not use an uninstaller to third parties as part of this process. This could permanently delete your Firefox profile data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and passwords saved. They can be retrieved easily unless they have been backed up on an external device! See back up and restore the information contained in the profiles of Firefox.

Please report to say if this helped you!

Thank you.

  • Windows XP home version suddenly does not, even in safe mode.

    My computer at home is no longer operational. Windows XP Home version has suddenly refused to load. It seems to start normally, but never ends. I tried to boot in safe mode. Although safe mode starts to load, it does not end. If I try to start normally or in safe mode, there is no error message. A few years ago, I bought the computer with XP preinstalled. It's never happened before. I have all the updates, including service pack 3. However; I realize now that I did a backup disk. Any advice as to what are my options?

    Given that your machine does not start, you need to start a system on a CD.  Easier to create CD's free Linux Livecd such asKnoppix.   If you have a friend with an XP installation disc, you can try to build a diskBelia PE or Ultimate Boot CD for Windows . On the chances that your problems of a corrupted registry, you can boot from that disk and use it to perform the steps in

    "How do I recover from a corrupted registry that prevents Windows XP startup"

    With a Live Linux disk, you can pick up the procedure in part 2, step 6 using Linux to copy, paste and rename the appropriate files.  If all else fails, you can use the same Linux Live CD to backup your data on a USB drive or a network drive before reinstalling Windows.  Most OEM computers have a recovery partition which is activated by pressing a particular key at the right time to start.  This procedure will completely erase the drive and put it in the State that it was when it was first purchased.  Quickly look up when you boot.  It is not stay there long.  If this does not work, you will need to get a replacement from the manufacturer of your computer installation disc.

    If the HP recovery process does not work, it seems to be a hardware problem.

    And now that you mention have a blue screen.

    If it was a software problem, the process of HP recovery to reinstall the operating system should fix (take it back in new condition).

    And this new condition would exclude any incorrect hardware drivers may have installed the original problem.

    Have you tried HP support?

    HP recovery process, you get the possibility of a destructive or non-destructive restore. If you use non-destructive recovery option, often have the same problems continue.

    The problem continues when you use destructive recovery too.

  • Indexing options and search for Windows 7 are not locate content of the document since "update" Open Office 3.3 3.4 (he worked for 2 years before that)?

    I have Win 7 with Service Pack 1. I have "updated my Open Office 3.3 to 3.4 and now Win 7 search and options DO NOT locate my document content indexing more? I contacted the support of Open Office: http://user.services.openoffice.org/en/forum/viewtopic.php?f=15&t=55483

    They claim that: "indexing and search in Windows 7 are performed by Windows 7", so there is a problem with Win 7 search and indexing options.

    I checked the indexing options in Windows 7 and the "Index Properties and content of the file" is selected for ALL the 'odt' as well as all the files 'o'.

    I set up a test document: I put only one word "Wednesday" in the Open Office text document, saved and it called "text". I am looking for Wednesday and the search comes up with two other documents containing the word Wednesday in them, but not the Test document?

    I just discovered something. When I did the 'Test' experience above, the file was saved in format 'odt' a:. I changed it to a ".doc" file and it now appears in the search results. As mentioned above, I've changed ALL the files starting with the letter 'o' in Indexing Options > Advanced Options > Types of files to the article: 'properties Index and contents of the file. The description of filter for files 'odt' comes back as: "IFilter shop OpenOffice IFilter" where as 'doc' filter is listed as a: «Filter Microsoft Office» Is it a "Boutique OpenOffice IFilter IFilter: issue" Blocking "the documents appear in the search results? If so, how should I do (I mean in addition to all the documents 'odt' replacing 'doc'?

    Just to clarify: document names 'odt' come to a search, but not the content document.

But now is not working and even after uninstalling and reinstalling firefox, it is inadmissible. I should have the version 6.0.2

  • System Restore does not work in windows 7? not even in administrator mode


    Sushant salvation,

    To help you better, please answer these questions.

    1 you get a specific error message?

    2. you try to restore the computer to an earlier time?

    3. you try to create a restore point?

    4 did you do changes on the computer before the show?

    I suggest you follow the provided methods to solve the problem.

    Method 1: Try to perform a system restore, safe mode.

    Start your computer in safe mode


    If you are able to perform the system restore in safe mode, I suggest you perform the clean boot and check that there could be some third-party application that may be causing the problem.

    Step 2:

    Put the computer in a clean boot state to see if there is a software conflict as the clean boot helps eliminate software conflicts.


    Note: After completing the steps in the clean boot troubleshooting, follow step 3 of the link to start the computer to a Normal startup mode.

    Important: If you use system restore when the computer is in safe mode, you can't undo the restore operation. However, you can run System Restore again and choose a different restore point, if any.

    Undo system restore


    Method 2

    You can also try temporarily disabling computer security software and check if it makes a difference. If the system restore works fine after you turn off the anti-virus, you can contact the manufacturer of security software and check if you need to change the settings

    Disable the antivirus software


    Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

    If the problem persists, perform the restore from Winre system.

    What are the system recovery options in Windows 7?


    Hope this information helps. If you have any other questions feel free to respond and we would be happy to help you.

  • After installing Win7 x 32 SP1, I can't launch Firefox. Not even in safe mode. I uninstalled Firefox and re-installed the program. Does not start.

    After you have installed SP1 Firefox stop working and Internet Explorer stop working. I can only use Chrome as browser at the moment.


    One possible cause is security software (firewall, antivirus) that prevents or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

    Delete all rules for Firefox and the plugin-container in the permissions list in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.


    Do a check with some malware malware, analysis of programs on the Windows computer.

    You need to scan with all programs, because each program detects a different malicious program.

    Make sure that you update each program to get the latest version of their databases before scanning.

    Alternatively, you can write a check for an infection rootkit TDSSKiller.
